In the original post the theory does not involve the Earth emitting anything. The particles are not gravitons as you are thinking of them, they are simply everywhere bombarding from all sides.
Why would the gravitons being emitted from the Earth be absorbed by the incoming ones?
Ok, that's quite a strange point to make but nevermind...
If the rain heats up the windshield(!), then heat will pass through the glass by conduction. The only way for the heat to leave the windshield (if we're in a vacuum) is by radiation which will push the windshield in the opposite...
You're saying gravity is the only attractive force, and there is some other force that repels everything? That gravity is the only attractive force and that it attracts matter but repels antimatter?
If that is what you're saying then how would your theory account for the experimentally...
Any analogy to do with general relativity is going to be very oversimplified. 4 dimensional space/time is a very different concept to the 3 dimensions of space and one of time that we know and love. Within relativity, (special and general) time is treated on completely equal footing to the...
Massless particles still carry momentum though. Photons carry momentum hf/c which is transferred when absorbed by matter. When photons are involved in particle interactions their momentum has to be taken into account.
If you read the editors notes about a book called Pushing Gravity (http://redshift.vif.com/BookBlurbs/PushingGravity.htm ) it tells you of a theory that describes the mechanism of gravity:
"The basic idea runs like this. Space is filled with minute particles or waves of some description which...
Hi
As far as I am aware the "sea of Dirac" was a concept that Dirac came up with to explain the existence of antiparticles - which he predicted from relativistic quantum theory.
Dirac noted that the equations (originally formulated for free electrons) permitted negative energy solutions...
